Summary
Early diagnosis of cranial sepsis is crucial to prevent complications. Imaging plays a key role in identifying infections like brain abscess and understanding their spread, aiding radiologists in diagnosis and management.
Area of Science:
- Radiology
- Infectious Diseases
- Neurology
Background:
- Cranial sepsis requires early diagnosis to minimize morbidity.
- Common sources include hematogenous spread or extension from sinuses.
- Infections can be focal (brain abscess, subdural/extradural empyema) or diffuse.
Purpose of the Study:
- To illustrate the role of imaging in cranial infections.
- To highlight diagnostic and management considerations for radiologists.
- To present a series of cases demonstrating imaging findings.
Main Methods:
- Review of cases with cranial infections.
- Analysis of imaging findings (e.g., CT, MRI).
- Correlation of imaging with clinical presentation and pathology.
Main Results:
- Imaging effectively identifies focal and diffuse cranial infections.
- Sinus disease is a frequent precursor to cranial sepsis.
- Specific pathogens like tuberculosis, lyme disease, and listeriosis have distinct imaging features.
Conclusions:
- Radiologists must be aware of imaging patterns in cranial sepsis.
- Prompt imaging is essential for timely diagnosis and treatment.
- Considering sinus disease history is vital for identifying infection sources.
